2EZ19D/TR8

The 2EZ19D/TR8 is a single zener diode used in a variety of applications, ranging from general purpose rectifying to protection from transient voltages and currents. It is designed to provide a single, unidirectional current path for diode protection.

The primary purpose of the 2EZ19D/TR8 zener diode is to protect electronic circuits from voltage spikes, known as transients. The zener diode can regulate a circuit’s power supply so that the voltage stays within the specified range, protecting the components from damage due to high voltages. The diode also helps protect circuits from electrostatic discharge and electrical noise.

The 2EZ19D/TR8 diode is constructed of two sections, each having its own anode and cathode. The anode of the diode is connected to the circuit’s power supply. When the voltage rises above the breakdown voltage, known as the zener-breakdown voltage, it will be diverted to the cathode of the diode instead of going to the circuit, thus protecting the components from damage.

The anode and cathode of the 2EZ19D/TR8 diode are designed in such a way that the anode is connected to ground and the cathode of the diode is connected to the circuit. This setup allows the diode to act as a current regulator, allowing a certain amount of current to flow freely through the diode whenever it is needed. This ensures that only the amount of current necessary for the circuit to function properly will flow.

As with any diode, the 2EZ19D/TR8 diode has an inherent amount of reverse leakage. Reverse leakage occurs when the voltage falls below the zener-breakdown voltage and a small amount of the voltage is diverted to the circuit. This small amount of current is known as reverse current and can be an issue if the circuit is not properly designed to allow it to flow.

The primary applications of the 2EZ19D/TR8 diode include protection from voltage spikes such as lightning strikes and transients caused by switching components, providing a current source for lighting circuits, and regulating the voltage of a battery supply. It can also be used in a variety of other applications including transistor and relay protection, serving as a rectifier, and providing a low current source for LEDs and other low power lighting sources.

The 2EZ19D/TR8 diode is a low cost, reliable, and effective diode for protecting circuits from unwanted voltage transients and other voltage irregularities. It can be used in a variety of applications to help ensure the safety and reliability of electronic components and systems.
